Hi jean:

Another issue is that you can set your elevation reference point in most Garmin units to either use the height above the ellipsoid or and approximation mean sea level.  This setting will also have an impact on your observed elevation.

Hi all .
I hope you are doing fine.
I have experienced an issue:
The elevation taken in the field with gps garmin64 is 623 m but the one given by SRTM download from Qgis is 612m.
How can I interprete this gap knowing that SRTM resolution is 30 meters.
